TECHNOLOGY AREA(S): Ground Sea
OBJECTIVE: The main objective is to design a high fidelity integration kit/technology allowing a Technology Readiness Level (TRL) 6 ABMS platform to be safely integrated onto an MRAP All-Terrain Vehicle (MATV). Then using modeling and simulation, install/mesh that design on a high fidelity three dimensional MATV; Take that high fidelity model and run it on Operational Mission Summary (OMS) 100 mile missions, that are Root Mean Square (RMS) of 30% Secondary, 30% primary, and 40% Cross Country, for 5,000 simulated miles. This will verify materials, system operation & integration reliability, significantly reducing risk of fielding, and verifying system safety. A break out of the model will do a simulated blast & counter firing to verify full system functionality, and indicate maintenance indices.
DESCRIPTION: Currently global impulse from underbody blast events are still creating casualties. The army has global impulse reduction technologies that are at a TRL level six, as standalone systems, however further studies into integration and the technology that empowers integration are required, to raise TRL level of the integration technology on the selected platform. Base level integration studies have been done on FMTV, but not necessarily on front echelon vehicles which would be first candidates for fielding and subsequent integration. So the need to study integration technologies and design o f a TRL level 6 Active Blast Mitigation technology on an MATV or RG33 platform is needed immediately. The ideal course of action would be to design a high fidelity model with the ABMS system, with the integration technology and run it through high fidelity Modeling and simulation, in both blast and road load shock and vibe, increasing the TRL level of the integration technology. For road load shock and vibration, the final design and corresponding integration technology would be Road Load shock and vibration simulated in accordance with the MATV Operational Mission Summary (OMS) 100 mile missions, that are Root Mean Square (RMS) of 30% Secondary, 30% primary, and 40% Cross Country, for 5,000 simulated miles. This will verify the technology for integration, subsequent materials, system operation, & integration are reliability; significantly reducing risk, and verifying system safety. A break out of the model will do a simulated blast & counter firing to verify full system functionality, and indicate maintenance indices every 500 miles. This can be done quickly and effectively using the RMS profiles and model that is available at NATC.
PHASE I: Due to the forces imparted on a vehicle during an underbody blast, and the counter force of ABMS countermeasures the technology to integrate ABMS technology is just as important as the ABMS technology itself. ABMS works by sensing a blast under a vehicle, analyzing that blast, and then reacting to that blast very quickly. Vehicles like MATVs and other Mine Resistant Ambush Protected vehicles suffer from a capability GAP where casualties are due not to intrusion from underbody clast, but from deadly launch, flight and slam down; ABMS mitigates the accelerations the body feels during these events, effectively mitigating the forces felt from launch, flight, and slam down. Therefore Phase one will be to design develop an integration kit/technology to safely integrate a TRL 6 ABMS technology on to an MATV. Since adding more weight would decrease the overall mobility, automotive performance, and blast performance of the vehicle, thus counteracting the most important aspect of ABMS; so it is necessary that the kit is as lightweight and utilizes the most advanced lightweight materials possible. Build a high fidelity three dimensional model of that kit/technology design, and the corresponding materials with the ABMS technology selected.
PHASE II: Mesh all models, MATV vehicle, ABMS system, and integration technology/kit into the modeling and simulation program, and begin an M & S shock and vibration limited 500 equivalent mile simulated shack down. Using that Mesh all models, vehicle, system, and integration kit, and begin durability M & S study. The model will utilize Operational Mission Summary (OMS) 100 mile missions, that are Root Mean Square (RMS) of 30% Secondary, 30% primary, and 40% Cross Country, for 5,000 simulated miles. This will verify materials, system operation & integration reliability, significantly reducing risk of fielding, and verifying system safety. A break out of the model will do a simulated blast & counter firing to verify full system functionality, and indicate maintenance indices.
PHASE III: After the system, and integration design has been verified, physically prototype the system in the production intent, and deliver that system to TACOM. This physical prototype can then be tested at an ATEC facility, or utilized by a unit that is at high risk underbody blast incidents.
